public final class NotImplementedFunction extends java.lang.Object implements Function
NotImplementedFunctionException
). This error should alert the user that the formula contained a function that is not yet implemented.
(这是 Function 类的默认实现。默认行为是引发 POI 内部错误 (NotImplementedFunctionException)。此错误应提醒用户该公式包含尚未实现的功能。)

evaluate
in interface
Function
(在接口函数中求值)
operands
- the evaluated function arguments. Empty values are represented with
BlankEval
or
MissingArgEval
, never
null
.
(操作数 - 评估的函数参数。空值用 BlankEval 或 MissingArgEval 表示,绝不为 null。)
srcRow
- row index of the cell containing the formula under evaluation
(srcRow - 包含计算公式的单元格的行索引)
srcCol
- column index of the cell containing the formula under evaluation
(srcCol - 包含正在评估的公式的单元格的列索引)
ErrorEval
, never
null
.
Note - Excel uses the error code
#NUM! instead of IEEE
NaN, so when numeric functions evaluate to
Double.NaN
be sure to translate the result to
ErrorEval.NUM_ERROR
.
(评估结果,可能是 ErrorEval,绝不为空。注意 - Excel 使用错误代码 #NUM!而不是 IEEE NaN,因此当数值函数计算为 Double.NaN 时,请务必将结果转换为 ErrorEval.NUM_ERROR。)
